笔者从理论上论证了生产高质量中间产品的企业对生产低质量中间产品企业具有挤出效应,并且使用2000年~2006年中国海关数据进行了实证分析,采用单位产品价格作为出口中间产品的质量测度指标,考察市场份额最大企业的中间产品质量对其市场份额的影响。实证研究表明:以单位价格测度的产品质量对这些企业的市场份额具有正向影响,并且采用事后推理的方法证明这些企业采取了质量竞争策略。
The author argues theoretically that the enterprises producing high quality intermediate products have crowding-out effect on the production of low-quality intermediate products and the empirical analysis is made on the Chinese customs data from 2000 to 2006. The unit product price is adopted as the quality of the export intermediate products Measure the index to examine the influence of the intermediate product quality of the largest enterprise with the largest market share on its market share. Empirical studies show that the product quality measured by the unit price has positive influence on the market share of these enterprises, and the method of post-inference is used to prove that these enterprises adopt the strategy of quality competition.
